Safety and oncologic outcomes of total laparoscopic versus abdominal hysterectomy following diagnostic conization for adenocarcinoma in situ and stage IA1 cervical cancer: a multicenter retrospective study

Q: How does OCRA curate its research paper database?

OCRA indexes peer-reviewed papers from PubMed and CrossRef, enriched with MeSH terms, author profiles, and citation metrics. Papers are categorized by cancer type, research method, and clinical relevance.

Q: Can I search papers by MeSH term or author?

Yes. Use the search bar to filter papers by MeSH term, author name, journal, keyword, or cancer type. Each paper includes linked MeSH terms and author profiles for further exploration.

Q: How current is the paper database?

The database is updated regularly through automated ingestion from PubMed and CrossRef. Most papers appear within days of their PubMed indexing date.

Abstract

Background

While simple hysterectomy is the standard treatment for adenocarcinoma in situ (AIS) and stage IA1 cervical cancer, minimally invasive surgery has been increasingly adopted. However, evidence on the safety and efficacy of total laparoscopic hysterectomy (TLH) for these conditions remains limited. We compared the safety and efficacy of TLH and total abdominal hysterectomy (TAH) in patients undergoing simple hysterectomy following diagnostic conization.

Methods

We conducted a multicenter retrospective study of 196 patients with cervical intraepithelial neoplasia grade 3 (CIN3), AIS, or stage IA1 cervical cancer who underwent simple hysterectomy following diagnostic conization. Patients were divided into TLH and TAH groups, and intraoperative and postoperative complications and oncologic outcomes were compared.

Results

Operative time was significantly longer in the TLH group, whereas intraoperative blood loss was lower and postoperative hospital stay shorter. No significant difference was noted in severe complication rates, although their patterns varied between groups. Recurrence occurred in one patient (0.5%), a case of CIN3 at the vaginal cuff in the stage IA1 TAH group. No recurrences were observed in patients with AIS or stage IA1 disease in the TLH group.

Conclusions

TLH following diagnostic conization for AIS or stage IA1 cervical cancer demonstrated oncologic efficacy comparable to TAH, with a favorable safety profile. TLH may be a reasonable treatment option for carefully selected patients.
